Abstract

This study focuses on the investigation of rock slope stability using a drone-based thermal sensor. In this study, a compact remote sensor of visible spectrum (400–700 nm) and infrared thermography spectrum (7,500–13,500 nm) was used to develop a method for monitoring the stability of rock slope failure in terms of temperature. This study used two datasets of each sensor that were collected in two different phases. The first phase was conducted during the dry season, which was completed in October 2019. Meanwhile, the second phase was carried out during the wet season in December 2019. The study area is located at a rock slope structure of KM 257.5 to KM 258.3, which is approximately 800 m in length at the North-South Expressway (PLUS). The location is situated after the Menora tunnel in Jelapang, Perak, Malaysia, facing southbound. This study is helpful in illustrating how drone-based remote sensing is implemented in rock slope investigations. The results from this study indicate that rock slope instability can be identified through the thermal image of surface temperature. Finally, this study determines that a rock slope is less stable in cooler temperatures compared to warmer temperatures. Rock slope failure tends to occur at a cooler surface, especially for wedge and toppling failure.
